N2 - Seeds of the genus Weigela (Caprifoliaceae) are described from the Early Miocene Hannuoba Formation of Weichang County, Hebei Province, China. They are flat, elliptic, with translucent membranous wings on three sides. Comparison with extant and fossil species of Weigela
indicates that these seeds are different which therefore were assigned to a new species, Weigela weichangensis. On the basis of the fossil record, the distribution of Weigela through geologic ages is shown on a series of palaeogeographic maps of the Northern Hemisphere. The oldest
fossils of Weigela are seeds from the Oligocene of West Siberia, Asia. The genus later expanded into East Asia and Europe as well as into Arctic/Subarctic areas of North America via the North Atlantic Land Bridge and/or Bering Land Bridge in the Miocene. Weigela disappeared from
Europe and North America probably during the Pleistocene glaciations, but survived in Asia until now.
